We provide day loaners for chromebooks when students forget theirs, but want a way to disable the spare when it’s not returned by end of day. It was suggested I create a spare pool specifically for this which I have done and now want to test. It is named TL Chromebook Day Loaners and I put four spares in it to test. I create the below rule for assets to disable the device in the pool if it has a owner since it would be checked out to someone. so far nothing. Any thoughts and help would be greatly appreciated.
